Abstract (en)
[origin: EP1947707A1] This invention provides an organic electroluminescent element that has a thin and compact sealing structrue and is excellent in heat resistance in sealing, particularly a high-brightness organic electroluminescent element comprising a phosphorescence emitting substance, and a liquid crystal display device and lighting equipment using the same. The organic electroluminescent element comprises a substrate and a first electrode, one or more organic layers including a luminescent layer, and a second electrode provided on the substrate. An adhesive layer is disposed on the whole area of a light emitting surface and remote from the light takeout side in the organic electroluminescent element, and a flexible film having a barrier film is applied thereto to form the light emitting surface. The organic electroluminescent element is characterized in that at least one of the luminescent material contained in the luminescent layer is phosphorescence emitting substance, and not less than 80% by mass of the organic material constituting the organic layer has a glass transition temperature of 100°C or above.
